What is the bolt pattern on a Chevy Bolt?
The Chevy Bolt EV uses a 5-lug bolt pattern on a 105 mm pitch circle (5x105).
In practical terms, that means five wheel studs are evenly spaced around a circle 105 millimeters in diameter. The hub bore is typically about 56.6 mm, and the lug nuts are M14×1.5 with a 60-degree conical seat. Always verify these specs for your exact model year and wheel setup.
Bolt Pattern Basics
To help you shop for wheels, here are the core measurements you need to know when matching a Bolt EV wheel set.
- Lug count: 5
- PCD (bolt pattern diameter): 105 mm (4.13 inches)
- Hub bore: ~56.6 mm (2.23 inches)
- Lug nut size and seat: M14×1.5 with 60-degree conical seat
- Recommended lug-nut torque: ~140 ft-lb (190 N·m)
Before listing the key specs, note that the following details are specific to the Bolt EV and are the most commonly cited figures for factory and aftermarket wheels:
These specifications define compatible wheel sets; any wheel with a different bolt pattern or hub bore may require adapters or may not fit without modification. Always verify fitment with the wheel manufacturer and your vehicle’s documentation.
Practical Considerations for Wheel Upgrades
When swapping wheels onto a Chevy Bolt, you should also consider offset, backspacing, and brake clearance. The 5x105 pattern limits direct compatibility with many non-GM wheels, though aftermarket options exist. If a wheel has a larger bore, hub-centric rings can help achieve proper seating; if the offset or brake caliper clearance is off, rubbing can occur. Always confirm exact specs for your build year and wheel model.
Year-to-Year Variations
For the Bolt, the bolt pattern has remained consistent across model years in North America (and many global markets). However, you should confirm any minor differences in hub bore or lug nut specifications for European-market Ampera-E variants or special editions. When in doubt, consult GM’s official fitment guides or your wheel supplier’s compatibility charts for your exact year and region.
Summary
The Chevy Bolt EV adheres to a 5x105 bolt pattern with a ~56.6 mm hub bore and M14x1.5 lug nuts with a 60-degree conical seat, typically torqued to around 140 ft-lb. This pattern is a key filter when shopping for wheels or adapters, and always confirm year-specific specs and fitment with authoritative sources before purchasing.
